The task is to determine what the tolerances are for the MICE Demonstration of Ionisation Cooling lattice. Intention is to deliver tolerances to the engineering team and let them feedback where they are not practical; we can then assess the consequences.

The tolerance - i.e. allowable error - on each parameter should be determined for each of the following criteria. Some criteria will be more relevant than others (e.g. magnetic fields can never cause energy loss)

At what point does the output emittance of the cooling channel degrade by more than 1 (0.1) %?

At what point does the optical beta function at the absorber change by more than 1 (0.1) %?

At what point does the optical beta function at the downstream tracker change by more than 1 (0.1) %?

At what point does the mean position of particles in a matched, 6 mm emittance beam, change by more than the downstream tracker resolution (10 % of the D/S tracker resolution)?

At what point does the field uniformity in the tracker region degrade by more than 1 (0.1) %

At what point does the projection from tracker to PID detectors become dominated by the field errors (as opposed to multiple scattering, energy straggling, finite size of detectors)?

At what point does the energy loss/gain change by more than 1 % (0.1 %)?

At what point does the energy loss/gain change by more than 10 % (1 %) of the detector resolution?

At what point does the scattering in material change by more than 1 % (0.1 %)?

Note that I have put a loose tolerance and a tight tolerance on each specification. The loose tolerance means that analysis group would have to measure the effect and treat it in the analysis; the tight tolerance means that the analysis group would be able to treat the error as a systematic.
